The lingerie designer, 41, told ITV's Lorraine: "It’s two ravenous boys, breastfeeding them sometimes 14 times a day. They just suck the life out of you and weight.”

The Mum-of-two, who previously suffered a miscarriage and three failed IVF attempts, showed off her incredible post-pregnancy figure in black skinny jeans and a chic black top as she chatted away to the TV host.

Caprice and her millionaire partner Ty Comfort, 46, had hoped a surrogate would help end their baby heartache after doctors warned she was unlikely to conceive.

But after learning an American woman acting as their “gestational surrogate” was pregnant with their biological child, she found out she had conceived just one month later.

Thrilled Caprice said: “That was a miracle, even my IVF doctor said that was a miracle because of my medical condition. I took a test and then I took 10 more tests and I thought ‘oh my goodness, I can’t believe this.”

“I was in the room with my surrogate holding her hand and watching everything happen and then I cut the umbilical cord and then I quickly just took off all my top and I just put my son next to me and he stopped crying and we fell asleep together and it was really special,” she told Lorraine.

And a few weeks later she gave birth to her second son.

The model, who named her boys Jett and Jax, said she didn't want to make a big deal about the fact that one of her sons was born by surrogate.

"They're twins essentially... They're both biologically mine I just had a babysitter for nine months, a really great babysitter," Caprice explains.

"My surrogate is in our life and she is a very dear friend... she'll be known as Aunty.

"They're so loved. Both of them, exactly the same," the blonde beauty added.
